Area of triangle by heron's formula
= √[ s( s - a )( s - b )( s - c )] where,
s = ( a + b + c ) / 2
s = ( 20 + 20 + 24 ) cm / 2
= 64 cm / 2 or 32 cm
= √[32( 32 - 20 )( 32 - 20)(32-24)
= √[ 2⁴ × 2 × 2² × 3 × 2² × 3 × 2³ ]
= ( 2 × 2 × 2 × 2 × 2 × 2 × 3 )
= 192 cm²
Area of rhombus = 196 cm² × 2 = 384 cm²
\boxed{ Answer : 384 cm^2 }
